The following example shows one way of connecting MDM Server instances by setting
up a load balancing solution using mod_jk with Apache Tomcat. It assumes that you
already have some experience of working with httpd and have some knowledge of Apache
Tomcat and Apache Tomcat connectors (mod_jk).

Such a cluster consists of one Apache server that dispatches all the
incoming requests across the cluster, and two "nodes", which are different instances of
MDM Server installed on the same machine.

Procedure

Edit the configuration file
<Apache_home>\conf\httpd.conf.

Add the following lines:

JkMount /talendmdm/* loadbalancer
JkMountCopy all

Create a new file worker.property and
populate it as follows:

Make sure the workers listed for worker.loadbalancer.balance_workers correspond to names specified
for jvmRoute in the file
<TomcatPath>/conf/server.xml because Apache
server will dispatch the requests based on the file
worker.property.
